On a Pogo Stick

Posted by Rufus La Lone on

Monday June 17
Astronomical Summer starts this Thursday, as will a notable warm-up in the region’s temperatures.  Refill your morn’n Mug; time for our Monday update.
Cool temps will slowly yield to summer temps by the end of this week.  Currently, models have ‘done away’ with any threat for broad areas of precipitation during the next 10 days (exception - northern half of Vancouver Island next weekend).  The heat zone over the desert SW is modeled to briefly nudge to the NW by Thu & Fri, ushering in a short round of warm-to-hot temps for the PNW.   
Charts suggest a short cool-down over the coming weekend, as an onshore flow increases due to a weak Low pushing over northern Vancouver Island / SW BC.  Once that Low moves east, expect PNW temps to heat back up for another couple of days next Mon & Tue; then the pattern repeats.
Temps will drop some by Wed Jun 26 with onshore flow cooling down the region - pushing back at the heat trying to nudge in.  This time, the Low pressure trough could be strong enough to threaten showers around the PNW for a couple of days -> Thu & Fri Jun 27,28.
The last weekend of June 2024 continues to look partly cloudy, with a chance for showers (mainly the NW WA / Vancouver ls area).  Mild temperatures.  
As July gets underway, models suggest a couple days of HOT weather before another Low pressure trough presents an onshore flow by the 4th of July.  No bets just yet.  
Bottom line:  for the rest of June, regional temperatures will pop up & down like playing on a Pogo Stick.
